TMP422-EP: Thermal resistance

Carlo

Part Number: TMP422-EP

Hi E2E,

Good day.

Our customer is requesting for the junction-to-lead or junction-to-board thermal resistance of V62/11618-01XE. The datasheet only contains theta JA and theta JC.

Thank you in advance for your assistance.

Regards,
Carlo

Hi Ren,

Thank you for looking into this. Also, our customer would like to know if the thermal resistance of this device has been analyzed through finite element analysis or tested thermally in a vacuum chamber to see the resistance without an air gap? They're concern that it includes dissipation to ambient air and dissipation through an air gap to the board.

Regards,
Carlo
